Status indicator lights Highly visible status lights are located on both sides of the Autosampler. These lights correspond to the status indicator on the HI932 display and can easily be seen from far away. The lights double as a safety feature, as pressing them at any time will automatically stop the current titration sequence. • Steady green · Idle, ready to start • Flashing green · Titration sequence running • Flashing yellow · Titration sequence paused • Steady Red · Error or emergency stopped, or initializing during power on • Flashing Red · Error during sequence running or manual operation RFID recognition Sample trays are automatically detected and identified when placed on the Autosampler. Digital balance compatibility Sample weights are communicated when connected to a digital balance. Speedy sample entry Sample names can be automatically incremented for speedy sample identification. Peristaltic and Membrane Pumps • Up to three peristaltic pumps can be added at anytime • User replaceable pump systems • Peristaltic pumps · Uses high performance plastic that is engineered to be chemically resistant and have long service life. · Reagent addition, sample leveling, waste removal · Greater than 200 mL/min flow • Membrane pumps · Simple plug connection for tubing · Greater than 400 mL/min flow Users can add up to three peristaltic pumps or one membrane pump at any time with the user-replaceable pump systems on the HI922. The peristaltic pumps use high performance plastic that is engineered to be chemically resistant with a long service life. These pumps have a flow greater than 200 mL/min and can be utilized for reagent addition, sample leveling, and waste removal. The membrane pump is a simple plug connection for tubing that has a flow greater than 400 mL/min. 4 Titration 4.14 | www.hannainst.com
